The present invention is directed to a method of making such gypsum panel. For instance, the method comprises: providing a first facing material; providing a gypsum slurry including calcium sulfate hemihydrate, water, and a silicon containing compound onto the first facing material; providing a second facing material onto the gypsum slurry to form a continuous gypsum sheet; allowing the calcium sulfate hemihydrate to hydrate to form calcium sulfate dihydrate; cutting the continuous gypsum sheet to form a gypsum panel; supplying the gypsum panel to a heating or drying device; and providing a gaseous mixture from the heating or drying device to a regenerative thermal oxidizer.

Gypsum panels and methods for their manufacture are provided herein. The gypsum panels include a gypsum core having a first surface and a second opposed surface and a first fiberglass mat associated with the first surface of the gypsum core, such that gypsum from the gypsum core penetrates at least a portion of the first fiberglass mat.

Gypsum panels and methods of making the same are provided. A method of making a gypsum panel includes forming a first gypsum slurry by combining stucco, water, a siliconate, and a phosphate salt or polymer, and setting the first gypsum slurry to form at least part of a core of the gypsum panel, wherein the gypsum panel displays a 2-hour water absorption test weight increase of at least 10 weight percent less than an otherwise identical comparative panel containing no phosphate salt or polymer in its core.
